Definitions

  • This invention relates in general to the field of multi-station presses. More particularly, the present invention relates to a system and method for transferring a work piece in a multi-station press.
  • Sheet metal is used to form the basic components of many commercial products. For example, sheet metal is used to form parts for automobiles, appliances, airplanes and other mass produced items. To transform the sheet metal into an appropriately sized and shaped part, the sheet metal is pressed, bent, cut, pierced, trimmed, etc.
  • a transfer press is typically used to expedite the process of forming parts from sheet metal. Transfer presses typically include several upper and lower die combinations referred to as press stations that are arranged in a line within the transfer press. The dies for each press station are chosen to perform specified functions to create the desired part. Additionally, the transfer press includes an automated system that transfers the parts from one station to the next to increase the rate of output by the transfer press. Over the years, the size of parts formed from sheet metal have increased significantly.
  • Shiraishi and Schneider both disclose movement of a cross bar along a curved path from a rest position between stations to a first press station.
  • the part is transplanted from the first press station to a second press station over a curved path and the cross bar returns to the rest position between press stations.
  • the cross bar stays in the rest position during a press operation.
  • the Schneider patent also shows cross bar assemblies with carriages formed in a low-mass construction. This low-mass construction allows increased acceleration and thus the press may operate at a higher speed. Schneider also discloses idle stations disposed between each of the press stations to help in reorienting the part for subsequent processing. Although the idle stations may allow for shortening the transfer movements of the press, they also introduce a delay by adding extra stations.
  • the idle stations also require additional tooling.
  • the idle stations add to the possibility of damaging the work piece by doubling the number of times the work piece is handled.
  • the present invention includes in one embodiment a system for transferring a work piece in a multi-station press having a plurality of associated upper and lower dies.
  • the system includes at least one cross bar assembly that extends above the press stations perpendicular to the transfer direction of the press.
  • a plurality of holding devices are coupled to the cross bar assembly for removably engaging a work piece to be moved between the press stations.
  • the cross bar assembly moves in a cyclical manner between the press stations to move the work piece between adjacent first and second press stations.
  • the cross bar assembly begins in a first rest position adjacent to the second press station.
  • the cross bar assembly first moves into the first press station wherein the holding devices engage a work piece and move the work piece to the second press station.
  • the cross bar assembly next moves from the second press station to a second rest position.
  • the second rest position is located adjacent to the first press station.
  • the cross bar assembly returns to the first rest position. A predetermined portion of the movement from and to the rest positions may occur while the upper die is separated from the lower die by less than a maximum separation.
  • a technical advantage of the present invention includes in one embodiment that the cross bar assembly moves toward a first press station before the upper and lower dies are completely separated and moves away from a second press station while the upper die begins to move toward the lower die, thus increasing the speed and efficiency with which the press is able to transfer large work pieces.
  • each cross bar assembly may be programmed to provide dynamic orientation of the work piece during transfer between press stations.
  • each cross bar assembly includes a pair of opposite carriages. Two cross bars extend between each pair of carriages. The carriages are mounted on a pair of transfer rails that extend along the length of the transfer press.
  • Each carriage further includes a vertical member, a horizontal member and a rotational member. The vertical, horizontal and rotational members are coupled to the carriages such that the cross bars may be independently rotated translated vertically, and translated horizontally with programmability.
  • sets of vacuum cups are slidably attached to the cross bars. Each set of vacuum cups may move along the cross bar independently with programmability.
  • Another technical advantage of the present invention includes in one embodiment that it may be used to orient a work piece in a transfer press while moving the work piece from one station to the next thus eliminating the need for idle stations and increasing the rate of output of the transfer press.
  • the cross bar assembly can be programmed to tilt the work piece in the direction of flow or in a direction perpendicular to the direction of flow. Additionally, the cross bar assembly itself can be programmed to raise and lower the work piece with respect to the transfer rails.
  • cross bars may be stored close together in the rest position and may separate from each other when moving into a press station to engage and lift a work piece. This increases the speed and efficiency of the press by decreasing the space requirements for the rest positions and thus decreasing the overall distance travelled by the work piece in the transfer press.
  • cross bars may move in tandem so as to increase or decrease the effective distance that a work piece travels between press stations. This allows the press stations to be spaced at varying intervals along the transfer press while the cross bar assemblies are spaced at a fixed distance apart.
  • a cross bar assembly may transfer multiple parts simultaneously through the transfer press.
  • a cross bar assembly can be programmed to separate parts in the direction of flow. Additionally, the cross bar assembly can be programmed to separate parts perpendicular to the direction of flow. In fact, each set of vacuum cups could be used to transfer a separate work piece.
  • the transfer mechanism is not designed to be dedicated to a specific work piece.
  • the same cross bars and vacuum cup sets can be used to transfer a wide variety of work pieces without changing out the cross bars.
  • the transfer rails do not extend beyond the confines of the transfer press during operation. Rather, the carriages move back-and-forth on the rails the reducing the chance of inadvertent injury from horizontal movement of the transfer rails.
  • Another technical advantage of the present invention is that it includes an overload device which releases the cross bar if it hits an interference. This feature minimizes the damage to the cross bar.

Abstract

L'invention concerne une presse-transfert à postes multiples (10). Des ensembles de barres transversales (28) transfèrent les pièces à usiner (12) entre les postes (14) adjacents dans la presse-transfert (10). Chaque ensemble de barres transversales (28) assure le déplacement des pièces à usiner entre les multiples postes adjacents. Les mouvements des ensembles de barres transversales sont assurés par le soulèvement et l'abaissement de rails de trasfert (22) et (24) par le va-et-vient de barres transversales (28) le long des rails de transfert (22) et (24). Les ensembles de barres transversales (28) peuvent être actionnés pour orienter dynamiquement les pièces à usiner (12) lors de leur transfert entre les postes (14) adjacents de la presse. En outre, une partie du déplacement des ensembles de barres transversales (28) se produit lorsque la distance séparant les matrices supérieures (20) des matrices inférieures (18) est inférieure à une valeur maximale.
